How- ever, there are some problems on the aspect, including deficiency of law supports and top system design, less recognition on insurance of farmers and low effective demands of agricultural insurance market, huge agricultural risks and insufficient supply from agricultural insurance market, and shortage of reinsurance support and disaster risk desertification, hardly to deal with heavy disasters. Therefore, some countermeasures were proposed, including to formulate agricultural insurance laws and establish specific agricultural insurance management institutions, to reinforce promotion and improve premium subsidy system in order to increase market de- mands, to increase tax preference and operating costs, improve insurance services and enhance effective supply in market and to construct a risk diversification system of agricultural heavy disaster.展开更多
